32. Formats
Supported buffer and image formats may vary across implementations. A minimum set of format features are guaranteed, but others must be explicitly queried before use to ensure they are supported by the implementation.
The features for the set of formats (VkFormat) supported by the implementation are queried individually using the vkGetPhysicalDeviceFormatProperties command.
32.1. Format Definition
The following image formats can be passed to, and may be returned from Vulkan commands. The memory required to store each format is discussed with that format, and also summarized in the Representation and Texel Block Size section and the Compatible formats table.

32.1.3. Identification of Formats
A “format” is represented by a single enum value. The name of a format is usually built up by using the following pattern:
VK_FORMAT_{component-format|compression-scheme}_{numeric-format}
The component-format indicates either the size of the R, G, B, and A components (if they are present) in the case of a color format, or the size of the depth (D) and stencil (S) components (if they are present) in the case of a depth/stencil format (see below). An X indicates a component that is unused, but may be present for padding.
| Numeric format | Description |
|---|---|
|
The components are unsigned normalized values in the range [0,1] |
|
The components are signed normalized values in the range [-1,1] |
|
The components are unsigned integer values that get converted to floating-point in the range [0,2n-1] |
|
The components are signed integer values that get converted to floating-point in the range [-2n-1,2n-1-1] |
|
The components are unsigned integer values in the range [0,2n-1] |
|
The components are signed integer values in the range [-2n-1,2n-1-1] |
|
The components are unsigned floating-point numbers (used by packed, shared exponent, and some compressed formats) |
|
The components are signed floating-point numbers |
|
The R, G, and B components are unsigned normalized values that represent values using sRGB nonlinear encoding, while the A component (if one exists) is a regular unsigned normalized value |
The suffix _PACKnn indicates that the format is packed into an
underlying type with nn bits.
The suffix _mPACKnn is a short-hand that indicates that the format has
several components (which may or may not be stored in separate planes)
that are each packed into an underlying type with nn bits.
The suffix _BLOCK indicates that the format is a block-compressed
format, with the representation of multiple pixels encoded interdependently
within a region.
| Compression scheme | Description |
|---|---|
|
Block Compression. See Block-Compressed Image Formats. |
|
Ericsson Texture Compression. See ETC Compressed Image Formats. |
|
ETC2 Alpha Compression. See ETC Compressed Image Formats. |
|
Adaptive Scalable Texture Compression (LDR Profile). See ASTC Compressed Image Formats. |
For multi-planar images, the components in separate planes are separated
by underscores, and the number of planes is indicated by the addition of a
_2PLANE or _3PLANE suffix.
Similarly, the separate aspects of depth-stencil formats are separated by
underscores, although these are not considered separate planes.
Formats are suffixed by _422 to indicate that planes other than the
first are reduced in size by a factor of two horizontally or that the R and
B values appear at half the horizontal frequency of the G values, _420
to indicate that planes other than the first are reduced in size by a factor
of two both horizontally and vertically, and _444 for consistency to
indicate that all three planes of a three-planar image are the same size.
|
Note
No common format has a single plane containing both R and B channels but does not store these channels at reduced horizontal resolution. |
32.1.4. Representation and Texel Block Size
Color formats must be represented in memory in exactly the form indicated by the format’s name. This means that promoting one format to another with more bits per component and/or additional components must not occur for color formats. Depth/stencil formats have more relaxed requirements as discussed below.
Each format has a texel block size, the number of bytes used to store one texel block (a single addressable element of an uncompressed image, or a single compressed block of a compressed image). The texel block size for each format is shown in the Compatible formats table.
The representation of non-packed formats is that the first component specified in the name of the format is in the lowest memory addresses and the last component specified is in the highest memory addresses. See Byte mappings for non-packed/compressed color formats. The in-memory ordering of bytes within a component is determined by the host endianness.

Packed formats store multiple components within one underlying type. The bit representation is that the first component specified in the name of the format is in the most-significant bits and the last component specified is in the least-significant bits of the underlying type. The in-memory ordering of bytes comprising the underlying type is determined by the host endianness.

32.1.5. Depth/Stencil Formats
Depth/stencil formats are considered opaque and need not be stored in the exact number of bits per texel or component ordering indicated by the format enum. However, implementations must not substitute a different depth or stencil precision than that described in the format (e.g. D16 must not be implemented as D24 or D32).
32.1.6. Format Compatibility Classes
Uncompressed color formats are compatible with each other if they occupy the same number of bits per texel block. Compressed color formats are compatible with each other if the only difference between them is the numerical type of the uncompressed pixels (e.g. signed vs. unsigned, or SRGB vs. UNORM encoding). Each depth/stencil format is only compatible with itself. In the following table, all the formats in the same row are compatible.

32.2. Format Properties
To query supported format features which are properties of the physical device, call:
void vkGetPhysicalDeviceFormatProperties(
VkPhysicalDevice physicalDevice,
VkFormat format,
VkFormatProperties* pFormatProperties);-
physicalDeviceis the physical device from which to query the format properties. -
formatis the format whose properties are queried. -
pFormatPropertiesis a pointer to a VkFormatProperties structure in which physical device properties forformatare returned.
The VkFormatProperties structure is defined as:
typedef struct VkFormatProperties {
VkFormatFeatureFlags linearTilingFeatures;
VkFormatFeatureFlags optimalTilingFeatures;
VkFormatFeatureFlags bufferFeatures;
} VkFormatProperties;-
linearTilingFeaturesis a bitmask of VkFormatFeatureFlagBits specifying features supported by images created with atilingparameter ofVK_IMAGE_TILING_LINEAR. -
optimalTilingFeaturesis a bitmask of VkFormatFeatureFlagBits specifying features supported by images created with atilingparameter ofVK_IMAGE_TILING_OPTIMAL. -
bufferFeaturesis a bitmask of VkFormatFeatureFlagBits specifying features supported by buffers.
|
Note
If no format feature flags are supported, the format itself is not supported, and images of that format cannot be created. |
If format is a block-compressed format, then bufferFeatures
must not support any features for the format.
If format is not a multi-plane format then linearTilingFeatures
and optimalTilingFeatures must not contain
VK_FORMAT_FEATURE_DISJOINT_BIT.
Bits which can be set in the VkFormatProperties features
linearTilingFeatures, optimalTilingFeatures,

IfVK_FORMAT_FEATURE_BLIT_SRC_BITis also set, an image can be used as thesrcImageto vkCmdBlitImage with afilterofVK_FILTER_LINEAR. This bit must only be exposed for formats that also support theVK_FORMAT_FEATURE_SAMPLED_IMAGE_BITorVK_FORMAT_FEATURE_BLIT_SRC_BIT.If the format being queried is a depth/stencil format, this bit only specifies that the depth aspect (not the stencil aspect) of an image of this format supports linear filtering, and that linear filtering of the depth aspect is supported whether depth compare is enabled in the sampler or not. If this bit is not present, linear filtering with depth compare disabled is unsupported and linear filtering with depth compare enabled is supported, but may compute the filtered value in an implementation-dependent manner which differs from the normal rules of linear filtering. The resulting value must be in the range [0,1] and should be proportional to, or a weighted average of, the number of comparison passes or failures.
-
VK_FORMAT_FEATURE_TRANSFER_SRC_BITspecifies that an image can be used as a source image for copy commands. -

If a format does not incorporate chroma downsampling (it is not a “422” or “420” format) but the implementation supports sampler Y’CBCR conversion for this format, the implementation must setVK_FORMAT_FEATURE_MIDPOINT_CHROMA_SAMPLES_BIT. -
VK_FORMAT_FEATURE_COSITED_CHROMA_SAMPLES_BITspecifies that an application can define a sampler Y’CBCR conversion using this format as a source, and that an image of this format can be used with aVkSamplerYcbcrConversionCreateInfoxChromaOffsetand/oryChromaOffsetofVK_CHROMA_LOCATION_COSITED_EVEN. Otherwise bothxChromaOffsetandyChromaOffsetmust beVK_CHROMA_LOCATION_MIDPOINT. If neitherVK_FORMAT_FEATURE_COSITED_CHROMA_SAMPLES_BITnorVK_FORMAT_FEATURE_MIDPOINT_CHROMA_SAMPLES_BITis set, the application must not define a sampler Y’CBCR conversion using this format as a source. -

The following bits may be set in bufferFeatures, specifying that the
features are supported by buffers or buffer
views created with the queried
vkGetPhysicalDeviceProperties::format:
-
VK_FORMAT_FEATURE_UNIFORM_TEXEL_BUFFER_BITspecifies that the format can be used to create a buffer view that can be bound to aVK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFERdescriptor. -
VK_FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_BITspecifies that the format can be used to create a buffer view that can be bound to aVK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFERdescriptor. -
VK_FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_ATOMIC_BITspecifies that atomic operations are supported onVK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFERwith this format. -
VK_FORMAT_FEATURE_VERTEX_BUFFER_BITspecifies that the format can be used as a vertex attribute format (VkVertexInputAttributeDescription::format).
typedef VkFlags VkFormatFeatureFlags;VkFormatFeatureFlags is a bitmask type for setting a mask of zero or
more VkFormatFeatureFlagBits.
To query supported format features which are properties of the physical device, call:
void vkGetPhysicalDeviceFormatProperties2(
VkPhysicalDevice physicalDevice,
VkFormat format,
VkFormatProperties2* pFormatProperties);-
physicalDeviceis the physical device from which to query the format properties. -
formatis the format whose properties are queried. -
pFormatPropertiesis a pointer to a VkFormatProperties2 structure in which physical device properties forformatare returned.
vkGetPhysicalDeviceFormatProperties2 behaves similarly to
vkGetPhysicalDeviceFormatProperties, with the ability to return
extended information in a pNext chain of output structures.
The VkFormatProperties2 structure is defined as:
typedef struct VkFormatProperties2 {
VkStructureType sType;
void* pNext;
VkFormatProperties formatProperties;
} VkFormatProperties2;-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific structure. -
formatPropertiesis a structure of type VkFormatProperties describing features supported by the requested format.
32.3. Required Format Support
Implementations must support at least the following set of features on the listed formats. For images, these features must be supported for every VkImageType (including arrayed and cube variants) unless otherwise noted. These features are supported on existing formats without needing to advertise an extension or needing to explicitly enable them. Support for additional functionality beyond the requirements listed here is queried using the vkGetPhysicalDeviceFormatProperties command.
|
Note
Unless otherwise excluded below, the required formats are supported for all VkImageCreateFlags values as long as those flag values are otherwise allowed. |
The following tables show which feature bits must be supported for each
format.
Formats that are required to support
VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT must also support
VK_FORMAT_FEATURE_TRANSFER_SRC_BIT and
VK_FORMAT_FEATURE_TRANSFER_DST_BIT.

and only with VkImageType |
|||||||||||
Implementations are not required to support the
VK_IMAGE_CREATE_SPARSE_BINDING_BIT,
VK_IMAGE_CREATE_SPARSE_RESIDENCY_BIT, or
VK_IMAGE_CREATE_SPARSE_ALIASED_BIT VkImageCreateFlags for the
above formats that require sampler Y’CBCR
conversion.
To determine whether the implementation supports sparse image creation flags
with these formats use vkGetPhysicalDeviceImageFormatProperties or
vkGetPhysicalDeviceImageFormatProperties2.
